Description
Technical Field
The invention relates to the field of shoe product design, in particular to a shoe product design method based on reverse engineering.
Background
Reverse engineering (also called reverse technology) is a reproduction process of product design technology, i.e. a reverse analysis and research is carried out on a project standard product, so as to deduce and obtain design factors such as processing flow, organization structure, functional characteristics and technical specification of the product, and thus produce products with similar but not identical functions. Reverse engineering stems from hardware analysis in the commercial and military fields. The main purpose is to directly deduce the design principle of the product from the analysis of the finished product under the condition that necessary production information cannot be easily obtained.
Although many colleges and scientific research units are applied to research of CAD in the shoe manufacturing industry at home, the research is limited to more theories, and systems with practical values are few. And domestic shoe-making CAD research mainly aims at shoe last and sole design and shoe sample expansion and contraction, and is little involved in the fields of 2D/3D design of shoe upper samples and whole shoe image output, and further improvement and perfection are needed.

In order to achieve the purpose, the invention provides the following technical scheme: a shoe product design method based on reverse engineering comprises the following steps:
s1: measuring three-dimensional data of the shoe tree and measuring the shape, size and relative position of the shoe tree;
s2: marking various characteristic points and basic control lines on the three-dimensional data of the shoe tree according to the structural design principle of the shoe product;
s3: classifying the characteristic points and the basic control lines, dividing the three-dimensional data of the shoe tree into different parts according to different classifications, respectively fitting the three-dimensional data of the different parts into curved surfaces, and merging the curved surfaces to obtain an accurate three-dimensional model of the shoe tree;
s4: drawing the contour lines of different upper parts according to the marked characteristic points and the basic control lines, and fitting the curved surfaces of the parts to obtain 3D upper sample models of different shoe products;
s5: and thickening the curved surfaces of the shoe tree and the upper to complete the whole shoe model.
Preferably, the three-dimensional point cloud data of the last is measured by a three-coordinate measuring machine in the step S1.
Preferably, the characteristic points in the step S2 include points corresponding to human bones and human joints.
Preferably, in the step S3, the three-dimensional point cloud data is processed by Imageware software, the Imageware software processes the last point cloud data in a point-to-point manner to form a curve, and then processes the curve to form a curved surface.
Preferably, in the step S5, the curved surface is thickened by Shell command modification method, so as to form a three-dimensional solid with a thickness.
Compared with the prior art, the invention has the beneficial effects that: the invention directly carries out 3D design of the shoe product on the shoe tree three-dimensional model, and forms the whole shoe model by utilizing the reverse engineering technology, the marked characteristic points and the basic control lines, so that the shoe product is more convenient and direct in design.
Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
The invention provides a technical scheme that: a shoe product design method based on reverse engineering comprises the following steps;
s1: measuring three-dimensional point cloud data of the shoe tree, and measuring the three-dimensional point cloud data of the shoe tree through a three-coordinate measuring machine so as to measure the size, the shape and the mutual position of the shoe tree;
s2: according to the structural design principle of the shoe product, marking various characteristic points and basic control lines on the point cloud of the shoe tree, wherein the characteristic points comprise point positions corresponding to human bones and human joints, the basic control lines select some representative characteristic points through the design universality and are connected in a straight line, so that a basic frame of the upper sample of the shoe product is formed, and the basic control lines mainly serve as a scale of the upper sample, so that the basic outline of the upper sample is controlled, and a better visual effect is achieved;
s3: classifying the control lines, dividing the shoe tree point cloud into different parts according to different classifications, respectively fitting the different parts into curved surfaces, and merging the curved surfaces to obtain an accurate shoe tree three-dimensional model; processing the last point cloud data through Imageware software, dividing the last point cloud data into four parts, fitting the last point cloud data of each part into a curved surface in a point-to-point mode and a curve, and fitting the curved surfaces of the four parts to obtain a three-dimensional model of the last;
s4: drawing the contour lines of different upper parts according to the marked characteristic points and the basic control lines, and fitting the curved surfaces of the parts to obtain 3D upper sample models of different shoe products; fitting the characteristic points and the basic control lines of the upper part into a curved surface by using Imageware software in a point-aligning mode and a curve, and fitting the curved surface to form 3D upper sample models of different shoe products;
s5: thickening the curved surface of the part, and designing a heel and other auxiliary parts, thereby completing the whole shoe model; since the 3D upper model obtained in the above steps is a curved surface without thickness and the actual shoe sample piece has thickness, the curved surface needs to be thickened by Shell command modification method to form a three-dimensional entity with thickness.
